For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Below is the attached figure Figures 1 to 4 The technical solution of the utility model is further illustrated by specific implementation methods.

[0034] like Figure 1-4 As shown, an automatic water adding structure comprises a base 1, an air guide cylinder 2 and a water tank 3, wherein the air guide cylinder 2 and the water tank 3 are respectively installed on both sides of the top of the base 1, and the air guide cylinder 2 is used to generate water vapor;

[0035] A water tank 11 is provided inside the base 1, and the air guide cylinder 2 and the water tank 3 are respectively connected to the water tank 11;

[0036] The inner wall of the air guide cylinder 2 is provided with a water inlet hole connected to the water tank 11;

[0037] The bottom end of the inner wall of the water tank 3 is provided with a water injection hole 31 connected to the water tank 11, and a blocking component 4 is provided in the water tank 11;

[0038] The sealing assembly 4 includes a lever 42, a float 43 and a sealing plate 45. The float 43 is arranged at one end of the lever 42, and the sealing plate 45 is arranged at the other end of the lever 42. The sealing plate 45 is arranged above the water injection hole 31. The water in the water tank 11 is used to drive the float 43 to move so that the sealing plate 45 blocks or opens the water injection hole 31.

[0039] The blocking component 4 provided in this solution can control the opening and closing of the water injection hole 31 according to the water level in the water tank 11, thereby ensuring that the water level in the air guide cylinder 2 is in a constant water level environment, avoiding the phenomenon of dry burning of the air guide cylinder 2 and excessive water affecting the mist output.

[0040] Furthermore, when the water level in the water tank 11 is low, the float 43 drops due to gravity, and the other end of the lever 42 rises, causing the sealing plate 45 to rise, thereby opening the water injection hole 31; when the water level in the water tank 11 is high, the float 43 rises due to buoyancy, and the other end of the lever 42 drops, causing the sealing plate 45 to drop, thereby blocking the water injection hole 31 by the sealing plate 45.

[0041] like Figure 1-4 As shown, the blocking assembly 4 further includes a mounting seat 41, a push rod 44, a push plate 46 and a spring 48;

[0042] The push rod 44 is movably inserted into the water injection hole 31, and the sealing plate 45 and the push plate 46 are respectively arranged at the upper and lower ends of the push rod 44, and the sealing plate 45 and the push plate 46 are respectively located inside the water tank 3 and the water tank 11, and the outer sleeve of the push rod 44 is provided with a spring 48, and the upper and lower ends of the spring 48 are respectively connected to the outer bottom end of the water tank 3 and the top of the push plate 46, and the mounting seat 41 is fixed to the inner bottom end of the water tank 11, one end of the lever 42 is connected to the floating block 43, and the other end of the lever 42 is pressed against the bottom end of the push plate 46, and the end of the lever 42 close to the push plate 46 is rotatably connected to the mounting seat 41 through a rotating shaft.

[0043] Specifically, when there is no water in the water tank 11, the floating block 43 at one end of the lever 42 drops due to gravity, and the other end of the lever 42 tilts up to push the push plate 46 to move upward, and the push plate 46 drives the sealing plate 45 at the top of the top rod 44 to move upward. At the same time, the push plate 46 squeezes the spring 48, so that the sealing plate 45 no longer seals the water injection hole 31, and the water in the water tank 3 can flow into the water tank 11 through the water injection hole 31, and the water in the water tank 11 flows into the air guide cylinder 2 through the water inlet hole, and the air guide cylinder 2 heats the water to Generate water vapor; when the water entering the water tank 11 reaches the set amount, the float 43 floats on the water surface, the other end of the lever 42 drops, the spring 48 resets and the push plate 46 moves downward, the push plate 46 moves downward and drives the sealing plate 45 to move downward, so that the sealing plate 45 blocks the water injection hole 31, and the water in the water tank 3 cannot flow into the water tank 11 through the water injection hole 31, thereby avoiding the water level in the air guide cylinder 2 being too high and affecting the generation of water vapor, thereby achieving the purpose of automatically adding water to and controlling the water in the air guide cylinder 2.

[0044] like Figure 4As shown, the outer sleeve of the top rod 44 is provided with a sliding sleeve 47, and the side wall of the sliding sleeve 47 is provided with a plurality of brackets arranged around the top rod 44, and one end of each bracket away from the sliding sleeve 47 is connected to the outer bottom end of the water tank 3, and the outer sleeves of the plurality of brackets are provided with the spring 48.

[0045] Specifically, the sliding sleeve 47 can be provided to enable the push rod 44 to move up and down stably and smoothly in the water injection hole 31 .

[0046] like Figure 2-3 As shown, the bottom end of the air guide cylinder 2 is connected to a water boiling tank 12, and a heating element is provided at the bottom end of the water boiling tank 12. The water boiling tank 12 is arranged through the base 1, and the water inlet hole includes a first small hole 13 and a second small hole 121 which are connected to each other. The first water inlet hole 13 is arranged on the inner wall of the water tank 11, and the second small hole 121 is arranged on the inner wall of the water boiling tank 12.

[0047] Specifically, the sliding sleeve 47 can be provided to enable the push rod 44 to move up and down stably and smoothly in the water injection hole 31 .

[0048] like Figure 2-4 As shown, the water tank 11 includes a first water storage section 111, a second water storage section 112 and a diversion section 113, one end of the diversion section 113 is connected to the first water storage section 111, and the other end of the diversion section 113 is connected to the second water storage section 112;

[0049] The first water storage section 111 is located at the connection between the base 1 and the air guide cylinder 2, the first small hole 13 is located on the inner wall of the first water storage section 111, the second water storage section 112 is located at the connection between the base 1 and the water tank 3, the floating block 43 is located in the second water storage section 112, and the guide section 113 is located inside the base 1.

[0050] Specifically, the water in the water tank 3 flows into the second water storage section 112 through the water injection hole 31, the water in the second water storage section 112 flows into the first water storage section 111 through the guide section 113, and the water in the first water storage section 111 flows into the water boiling tank 12 through the first small hole 13 and the second small hole 121.

[0051] like Figure 2 As shown, the height of the connection between the diversion section 113 and the first water storage section 111 is higher than the height of the connection between the diversion section 113 and the second water storage section 112 .

[0052] Specifically, since the height of the connection between the diversion section 113 and the first water storage section 111 is higher than the height of the connection between the diversion section 113 and the second water storage section 112, the water in the second water storage section 112 will flow into the first water storage section 112 through the diversion section 113 only when the water level in the second water storage section 112 is higher than the height of the connection between the diversion section 113 and the first water storage section 111.

[0053] It is worth noting that the floating block 43 is located in the second water storage section 112 , so that the blocking component 4 opens and closes the water injection hole 31 according to the water level in the second water storage section 112 .

[0054] like Figure 2-3 As shown, the first small hole 13 is arranged on a side of the first water storage section 111 away from the diversion section 113 .

[0055] Specifically, the first small hole 13 is disposed on a side of the first water storage section 111 away from the diversion section 113 , so that a certain amount of water can be retained in the first water storage section 111 .

[0056] like Figure 2-3 As shown, the distance between the first small hole 13 and the inner bottom end of the first water storage section 111 is smaller than the distance between the second small hole 121 and the inner bottom end of the water boiling tank 12 .

[0057] Specifically, since the distance between the first small hole 13 and the bottom end of the first water storage section 111 is smaller than the distance between the second small hole 121 and the bottom end of the boiling water tank 12, water can flow into the boiling water tank 12 only when there is water in the first water storage section 111 and the water level overflows the first small hole 13 and the second small hole 121, and the water level in the boiling water tank 12 is flush with the water level in the first water storage section 111, thereby ensuring that there is a certain amount of water in the boiling water tank 12 and avoiding the phenomenon of dry boiling in the boiling water tank 12.

[0058] like Figure 1-4 As shown, a humidifier with the automatic water adding structure as described above is characterized in that it includes a body 5 and an air outlet component 6;

[0059] The base 1 and the air guide cylinder 2 are arranged inside the fuselage 5. A mounting groove connected to the water tank 11 is provided on one side of the top of the fuselage 5. The bottom end of the water tank 3 is installed in the mounting groove. A sealing cover is provided on the top of the water tank 3.

[0061] Specifically, the water tank 3 is installed in the installation groove, which can facilitate the disassembly and assembly of the water tank 3 and the fuselage 5, so that the water tank 3 can be taken out for cleaning. When water is needed, the cover is opened to add water into the water tank 3. When water is not needed, the water tank 3 is sealed by the cover to prevent water in the water tank 3 from leaking.

[0062] It is worth mentioning that a heating element is provided at the bottom of the water boiling tank 12 to heat the water in the water boiling tank 12 to generate water vapor. The heating element can be a PCT heating element. The water vapor in the water boiling tank 12 flows upward into the air guide tube 2. Under the action of the air outlet component 6, the water vapor in the air guide tube 2 is sent to the outside of the fuselage 5 to humidify the external environment.

[0063] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way.
